Description of problem:
running xscreensaver-demo and displaying atlantis causes the screen to blank and
then become unresponsive. Keyboard commands, including <ctrl>-<alt>-<f1> have no
effect. The cursor continues to follow mouse movement, but mouse clicks have no
effect.

displaying the screensaver "pipes" displays the error:
pipes: sis_mesa.c: sis_SetDrawBuffer: Assertion `0' failed.
xscreensaver: child pid <nnn> (pipes) terminated with SIGABRT.




Version-Release number of selected component (if applicable):


How reproducible:

Steps to Reproduce:
1.run xscreensaver-demo
2.select pipes or atlantis
3.press the demo button
	

Actual Results:  if atlantis is selected, the screen blanks and freezes. if
pipes is selected it returns the error:
pipes: sis_mesa.c: sis_SetDrawBuffer: Assertion `0' failed.

Comment 1 Gregg Lebovitz 2002-05-21 22:06:19 UTC

upgrading Gnome to the Ximian Desktop fixes the problem with the "pipes"
screensaver, but doesn't affect the problem with the "atlantis" screensaver.

The problem with the "atlantis" screensaver is critical since it hangs my
desktop and cannot be corrected by killing X or gdm.

Comment 2 Bill Nottingham 2002-05-22 16:21:03 UTC

This is almost certainly an issue with the XFree86 drivers, or possibly the
kernel DRM drivers.

Comment 3 Mike A. Harris 2002-05-26 04:23:20 UTC

Disable DRI in your X config, and report back if the problem goes away.

Comment 4 Gregg Lebovitz 2002-05-29 16:00:34 UTC

Disabled the DRI modules and it corrected the problem.

Comment 5 Mike A. Harris 2002-09-12 04:39:07 UTC

This problem is believed to be fixed now, and affected pretty much
all DRI enabled drivers.  Please test the latest rawhide X and
kernel either using the Red Hat Linux (Null) beta, or once the new
release of Red Hat Linux is completed and released.  After testing
this out with our latest kernel/X, please provide updated status, and
if the problem persists, please attach your X server log and config
file.

Please test this out with DRI enabled to see if it works properly
with the latest package releases.

Comment 6 Mike A. Harris 2002-12-17 21:11:31 UTC

Assuming problem is fixed in current kernel update as described above
due to lack of response.

Closing as ERRATA.
